Application vfiled November 30, 1906. Serial No. 346,7 38.

To a/ZZ whom it may concern:

Be it known-that I, ROBERT MATTHEWS, a citizen or' the United States,residing at Seattle, in the county of King and State of"-Washingtoinhave' invented certain new and usef'ullmprovements inChairs, of which the yfollowing is a s ecification, reference being hadtherein. to t ie accompanying drawings.

f RM-y invention relates to chairs havin a 'tableflike support forconveniently holding `various objects' and 'which are peculiarly"adapted ier usein lunch rooms,libraries and the like; and its -objectisto provide a chair -l n of this characterwhich will permit of muchhaving the table-leaf thereon readi able to various desired horizontalpositlons.; To these ends the invention consists in the freedom ofmovementto the occupant, a11d yadJuStnovel construction and combinationof parts as will be hereinafter described and shown in Athe saiddrawings, in which- -Figure l` is a side elevation of a chair embod'yin.myinventiom the back being shown "partly l2 5.

under-siderview ofthe leaf-arm With P01" zbroken away g Fig. 2, a planview of the same, 'similarly broken away; Fig. 3, an

tions of the chair sup ort and brace; and Fig. 4, a cross sectiona Viewtaken-through 4--4 in Fig. 2, drawn to an enlarged scale.

, yThe reference numeral 5 designates the seat of a cli-air, 6 the legs,having connecting rounds such as' 7., and Sthe standards made byprolonging the rear legs upwardly and which with the connecting bars 9form the back thereof.

Rigidly connected toyone oi the standards, desirably that to the lefthand side of a person occupying the chain is a horizontal arm 10 whichis also supported upon the upper end of an inclined brace l1. This braceis secured to the adjacent rear leg and also to the frame of the seatand disposed to be at some distance from the iront edge of the seat toallow the occupant putting .his leg tlierebelow should he so desire.Rotatably mounted. upon said support is a leaf l2 with itsI pivotalconnection disposed `adjacent of one of its corners to allow ofits beingswung horizontally above a sitters lap upon occasionor to the sidewhennot in use.

Secured to the underside of the leaf is a f flanged socket 13 andanother like fixture 14.- l is attached to the bottom of the arm with'its boss 14 extending into an aperture LO of the arm. These two socketsare screw .threaded internally tov receivel the threads provided uponthe ends of a 'tubular member 15 and the threads are iii/this bothright^han'dsuch that when Vrthe leaf is swung over theA front of thechair the ends of the member 15 will be caused to further enter one orboth of the sockets and accordingly draw the lear` into closer relationwith the arm, or vice versa, when theleaf is swung outwardly. Interposedbetween the" two sockets is an extensible helical s ring 16- adapted totake up any loosenessw ch mayeventuate by the wearing of the screws andlikewise exerting a constant pressure upon the leaf preventing, thelatter being swung eXce t throughl the application of anappre# toV ciabe amount of force. Fixedly secure the underside of said leaf, as byscrews, are

two ormore metal attachments 19 each of which has an oil-set'end 19 toIembrace a metal bearing-track 20 upon the arm por- 'tion '10. Saidbearing-track is 'fixedly connected to said arm, as 'by screws 21and theportion which coacts with the attachments 19 is made concentric to theaxis of leaf pivot 15. y 22 is a pin projecting from the underside ofthe leaf for the purpose of limiting the rotary travel of the leaf byinterceptlng with the arm portion 10. .t Upon one of the bars or slats 9ofthe chairback and at ornear the level of the arm 1l) I provide anelbow rest 23 formed desirably of wood or material corresponding to thedesign of the chair and made somewhat wider than the thickness of theslat.

From the foregoing it is obvious' that thev loo the arni .suchconnection being adapted to shorten gthe distance between the arm andthe leaf when'the latter is-swung in one dlrection and to increase suchdistance when swung oppositely, and a spring interposed between said armand leaf.

'Ilo

2. ,A chair an arm with atrack-l' bearin for a superposed leaf, saidleaf, and pivota connections between said arm and the leaf .adapted toshorten when moved in one direction said connections consisting of atubular member provided with screw-threadone direction said connectionsconsisting of a tubular member provided with screw-threaded ends whichregister with sockets respectively secured to said arm and saidleaf.

4. In a chair having a single arm, Vprovided with a track-bearing for asuperposed leaf,

and said leaf, incombination with a pivotal connection between said armand saidleaf whereby the latter can be rotated into-various positions,and a spring acting to pressi apart the leaf and arm.

' 5. In a chair, the combination of an arm provided with a track-bearingfor asuperposed leaf, said leaf, andpivotal' connections between saidarm and said leaf and consisting of a tubular member provided withscrew-threaded ends which register with sockets respectively secured tosaid arm and to said' leaf, and4 an interposed spring tending toseparate said leaf from said arm.

6. n combination with the arm of a chair.'

and a leaf, of thepivotal connection between said arm and leaf,comprising flanged sockets provided with internal screw-threadsrespectively secured to said parts, anda tubular member-havingscrew-threaded ends which respectively enga e with said-sockets.

In testimony w ereof I affix my signature in presence of two witnesses.
